Too narrow for vintage bridge. Spaces in between saddles allow high E & B to slide laterally when aggressive bending is used. Height adjustment screws are all the same length and extend over the top of the saddle in the E's,A & B strings where action is lower. This rips the side of your hand open when muting at the bridge. I set my action higher than average so this could be worse for some. Solid block saddles do seem to improve tone marginally on my hard tail Strat.
